Nasdaq implements faster IPO entry and new free-float weighting rules
15 articles · Updated · The Wall Street Journal · May 3
The changes took effect Friday, allowing Nasdaq-listed IPOs big enough for the top 40 to enter after 15 days and capping weight at the lower of full value or three times free float.
Nasdaq also scrapped a 10% minimum free-float requirement, aiming to avoid distortions for low-float giants and likely increasing Arm Holdings' weight after next month's Nasdaq-100 rebalance.
The move comes as expected listings such as SpaceX, OpenAI and Anthropic push index providers to speed inclusion, with passive funds and ETFs including the $400 billion Invesco QQQ facing greater exposure.

How Nasdaq’s New 15-Day Fast-Track and Low-Float Rules Threaten Passive Investors in QQQ
Overview
In response to intense competition with the NYSE and the rise of mega-IPOs like SpaceX and OpenAI, Nasdaq implemented key rule changes in 2026, including a 15-day fast-track entry, removal of the 10% free-float minimum, and a 3x low-float cap multiplier. These changes enable rapid inclusion of large, low-float companies into Nasdaq indices, driving forced buying by passive funds that can artificially inflate stock prices. This creates risks of wealth transfer from passive investors to insiders when lock-up periods expire, impacting millions of retail investors. Meanwhile, Nasdaq tightened listing standards for smaller companies, reshaping the IPO market and sparking debates over index provider neutrality and regulatory oversight.
